Would an Asus gtx980ti Strix be more silent than an Msi 6G under load?

I've seen 8 pin to 2x fewer pin connectors, but I haven't seen an 8pin to 2x 8pin cable.

I guess the trouble is there are multiple reasons not too and people think they can skimp on it because they have a honkin single-rail psu w/o thinking about exceeding limits of the cable or connectors. If you just used one plug, you wouldn't get very far along at all since the power draw would easily exceed the cards per-connection current limit. If i didn't hate nannystate mentality so much, it might be a feature if the card didn't even let you run it with only 1 plugged in.

If you're referring to me, that is not what I mean at all. PureBlackFire has it right - 1 cable with a split-end connector that produces 8+8 pins to the GPU. I am connecting all 16 pins to my GPU, but since it's split, the base only has 8 pins connected to the PSU. The part that melted was the base.

that's the downside to psu manufacturers doing this. if someone wants to use a card that pulls more than 325 watts through the pci-e cable, user must be wary. these type of cable implement is not advisable for dual gpu cards like the R9 295X2 either. it has two Hawaii gpus and although they are much more efficient than the gpu in other hawaii based cards you are still putting 1.6x to double the amps through the twp pci-e connectors and one cablevs four seprate pci-e conectors and two + cables on a crossfire setup.

Ah, guess I've never seen a 8+8 split before. I've always heard people running one 8pin to power their 980ti. Which technically split or not its the same thing really. Split is probably more risky though.

the only concern one should have about running a single power cable to both a 6pin & 8pin connector, is the gauge of the wire and the quality of the plastic used for the connectors.

Dont change this though
PCIE Slot 75w


My PSU is Super Flower Leadex Platinum 1000W. http://www.jonnyguru.com/modules.php?name=NDReviews&op=Story2&reid=340


Based upon your advices I have modded (but not flashed) my card's bios so could you please check is there everything ok in your opinion. My goal is to rise TDP 110 -> 130% and nothing else. Thanks in advance!











Or would it be better to put 350 instead of 325W? :thinking.gif

So for example my graphics card comes with 2x8pin connector does that mean I can only get 375w max out of the card and nothing more?

nope. you can change the power limits in the BIOS and even without doing so you could go over that, if only until the card throttles back. remember, cards like the Titan X and 295X2 have two 8-pin connectors and of course those can use way more than 375 watts at load.

1 - your 6pin
2 - your 8pin
3 - max tdp

Only ones you should modify. For tdp to 130% just change 3 to 130% in max. Thats all as pcie, 6pin , 8pin are already set to max at 358w
